On another note, if you truly find the site useful, you should be interested in its longevity. For all you know, a team of 7+ with an affiliate sales model and only 60,000 monthly uniques may not have been able to sustain this product without interest from a larger corporate entity.
In essence, a sale is not synonymous with disappearance, and sometimes it can even _ensure_ the opposite.
On the other hand, I am happy these guys got their payday. They built an awesome site and totally deserve it.
Here's to hoping that eBay doesn't screw up the site too badly...
